Police and Mr Tostee's lawyers are using an audio recording of the night's events - taken from Mr Tostee's phone - as part of their evidence in the cases.

According to an affidavit from defence lawyers, Mr Tostee asked Ms Wright to stop attacking him before their conversation calmed down.

"...She appears to be seeing/hearing people who are talking to her...the deceased says she wants to look out the window. [Mr Tostee] says 'Don't jump off, or anything'...The deceased says 'No, I'm good'," the affidavit said.

Mr Tostee then joked that people in "white coats" were coming to the door, to which Ms Wright allegedly said: "Nah, I'll just jump off the balcony and like f***ing".

The full transcript prepared by Mr Tostee's lawyers was barred from publication, however the police version was released during a bail hearing in September.

The exchange was also highlighted in the police transcript and occurred about 40 minutes before Ms Wright's death. However their entry of that conversation contained typographical errors and did not clearly include her supposed statement.

Police claim toxicology results will show Ms Wright was drunk at the time having drunk home-distilled vodka, however there was no clear evidence that Mr Tostee was impaired.

In the minutes before Ms Wright's death, a struggle in the apartment broke out and Mr Tostee allegedly said: "You are lucky I haven't chucked you off my balcony you God damn psycho bitch".

His lawyers claim Ms Wright then armed herself with a heavy object and Mr Tostee managed to restrain and lock her out on the 14th-floor balcony in self-defence.

However police argue that the decision to put Ms Wright outside was an act of deprivation of liberty, which led her to seek an escape route.

Mr Tostee's lawyers' transcript also contained an exchange recorded between Mr Tostee and his father Gray soon after Ms Wright's fall.

Mr Tostee allegedly said: "God I hope, I hope she's not dead" and "If anything's wrong it would show up on the news wouldn't it?".

The 28-year-old has been released on bail under strict conditions, which include a ban on contacting women on the dating app Tinder, a curfew, rehabilitation for alcoholism, and a requirement to live at his parents' Gold Coast home.

Investigators are expected to complete their full brief of evidence against Mr Tostee by April, with a trial likely to occur in 2016.
